What is the short-run price elasticity of supply?

Answer 1

Answer :

Meaning & formula of short run price elasticity of supply,  its numerical example as per given case

Explanation:

Short Run Price Elasticity of Supply denotes the proportionate change in quantity supplied due change in price. Price & quantity supplied  change in same directions, as per law of supply.

In given case, increase in price of haircut increases the quantity supplied of the service of haircut, by more per labour service rate or more labour.

Short Run price elasticity of supply = percentage change in quantity supply/  percentage change in price =

Eg : If price increases from 5 to 10, & 5 workers' haircut increase from 4 to 6 haircuts for each worker, then total haircuts increase from 4 x 5 = 20 to 6 x 5 = 30

Short Run Price Elasticity of supply = 100/50 = 2
